Kenny has 13 TDs in 25 games. He straight up needs to put up those stats next year to have any confidence moving forward, but on his realistic trajectory, just reaching 25 career TDs next year with be a big accomplishment. Up until his senior year, he had a poor TD:INT ratio through his first three years before he exploded. To be fair, the Steelers did not set Pickett up for success, particularly with a porous OL and a terrible OC who did not play to Pickett's strengths. However, Pickett's faults have been exposed and even amplified in the NFL as he is facing tougher defenses. It's tough to lead a team when none of your strengths show up and all of your weaknesses are highlighted.
In the perfect world, if they're sticking with Pickett, I sign either a legit C or RT in free agency. I trade DJ and package a pick to move up and get one of the stud receivers (Rome Odunze would be my top target). Then grab a starting C or RT in the second round. Again, use one of the 4ths to move up. It's not a deep draft, so get quality while you can.
Five legit pieces along the OL, a backfield with Harris and Warren, two-deep at TE, with Odunze, Pickens, and hopefully a WR3 not named Allen Robinson is a strong foundation for any QB.
